Brian, you don’t understand what conservation of charge means. The net charge in a capacitor is always zero. The positive and negative sides of the capacitor have equal and opposite charges regardless of the voltage across the capacitor. So, your circuit starts with zero net charge and finishes with zero net charge.
Interesting work. You've done a good job here. My only concern is the very low initial voltages you measured on C2. If there was an offset error in your multimeter it could potentially manifest as an apparent increase in charge. I think to be more complete you might consider including the error of the voltage measurements. So, each value of apparent charge discrepancy in your table would end up having its own error.
